BACKGROUND OF THE INVENTION

[0003] 1. Field of the Invention

[0004] The present invention relates to a light emitting diode (LED)warning signal light having modulated power intensity for use byemergency vehicles. More particularly, the present invention is directedto a modular warning light signal system having interchangeableremovable and replaceable LED modules.

[0005] 2. Description of the Related Art

[0006] Light bars or emergency lights of the type used on emergencyvehicles such as fire trucks, police cars, and ambulances, utilizewarning signal lights to produce a variety of light signals. These lightsignals involve the use of various colors and patterns. Generally, thesewarning signal lights consist of revolving and oscillating lamps havingreflective back support members and colored filters.

[0007] Many problems exist with the known methods for producing warninglight signals. One particular problem with known light bars is theirreliance on mechanical components to revolve or oscillate the lamps toproduce the desired light signal. Additionally, these componentsincrease the size of the light bar or emergency lights which mayadversely affect the vehicles aerodynamic characteristics. Moreover,there is an increased likelihood that a breakdown of the light bar willoccur requiring the repair or replacement of the defective component.Finally, the known light bars require a relatively large amount ofelectrical current during operation. The demands upon the electricalpower system for a vehicle may therefore exceed available electricalresources reducing optimization of performance.

[0008] The most common light sources being used in light bars oremergency lights include halogen or incandescent lamps or gaseousdischarge xenon lamps. These lamps emanate large amounts of heat whichis difficult to dissipate from a sealed light bar or emergency light andwhich may damage the electronic circuitry contained therein. Inaddition, these lamps consume large amounts of current requiring a largepower supply, battery, or electrical source which may not be availablewithin a vehicle. These lamps also generate substantial electromagneticemissions which may interfere with radio communications. Finally, theselamps, are generally not rugged, and which have a relatively short lifecycle necessitating frequent replacement.

[0009] Another problem with the known warning signal lights is the useof filters to produce a desired color. Filtering techniques produce moreheat that must be dissipated. Moreover, changing the color of a lightsource requires the physical removal of the filter from the light bar oremergency light and the insertion of a new filter. Furthermore, filtersfade or flake rendering the filters unable to consistently produce adesired color for observation in an emergency situation.

[0010] The problems associated with traditional signaling lamps areexacerbated by the fact that creating multiple light signals requiresmultiple signaling lamps. Further, there is little flexibility inmodifying the light signal created by a lamp. For example, changing astationary lamp into one that rotates or oscillates would require asubstantial modification to the light bar which may not be physically oreconomically possible.

[0011] The present invention relates to electrical lamps, andparticularly the invention relates to high brightness light-emittingdiode or “LED” technology which operate to replace gaseous discharge,halogen, or incandescent lamps as used as emergency warning lightsources. The present invention is specifically directed to a modularsystem which includes one or more light supports onto which one or moreLED cards or modules may be readily connected thereto. The LED module(s)and the light support(s) respectively may have a variety of shapes andsizes. Individual LED modules may be configured to provide specificlighting characteristics such as various color configurations. As aresult, the LED modules may be arranged upon the light support(s) toprovide a warning signal light which may be readily manipulated andreconfigured be adding modules, removing modules and re-arrangingmodules on various surfaces of the support(s) to establish a desiredtype of warning lighting effect.

[0012] Illumination lamps for automobile turn signals, brake lights,back-up lights, and/or marker lights/headlights frequently haveaccompanying utility parabolic lens/reflector enclosures which have beenused for utility warning signals or emergency vehicle traffic signaling.

[0013] These signaling devices are commonly referred to as “unmarkedcorner tubes,” or “dome tubes”. These signaling devices frequentlyutilize xenon gaseous discharge tubes or incandescent lamps as theillumination sources.

[0014] A problem with the prior art is the cost and failure rate of theknown “unmarked corner tubes,” or “dome lights”. The failure rate ofthese devices frequently results in significant amounts of “down time”for a vehicle to effectuate repair or replacement. Further, an officeris typically unaware that a vehicle light is inoperative requiringreplacement. This condition reduces the safety to an officer during theperformance of his or her duties. In addition, the reduced life cycleand failure rate of the known illumination devices significantlyincreases operational costs associated with material replacement andlabor. A need, therefore, exists to enhance the durability, and toreduce the failure rate, of illumination devices while simultaneouslyreducing the cost of a replacement illumination source for a vehicle.

[0015] In the past, the xenon gaseous discharge lamps have utilized asealed compartment, usually a gas tube, which may have been filled witha particular gas known to have good illuminating characteristics. Onesuch gas used for this purpose was xenon gas, which providesillumination when it becomes ionized by the appropriate voltageapplication. Xenon gas discharge lamps are used in the automotiveindustry to provide high intensity lighting and are used on emergencyvehicles to provide a visible flashing emergency signal light.

[0016] A xenon gas discharge lamp usually comprises a gas-filled tubewhich has an anode element at one end and a cathode element at the otherend, with both ends of the tube sealed. The anode and cathode elementseach have an electrical conductor attached, which passes through thesealed gas end of the lamp exterior. An ionizing trigger wire istypically wound in a helical manner about the exterior of the glasstube, and this wire is connected to a high voltage power sourcetypically on the order of 10-12 kilowatts (kw). The anode and cathodeconnections are connected to a lower level voltage source which issufficient to maintain illumination of the lamp once the interior gashas been ionized by the high voltage source. The gas remains igniteduntil the anode/cathode voltage is removed; and once the gas ionizationis stopped, the lamp may be ignited again by reapplying theanode/cathode voltage and reapplying the high voltage to the triggerwire via a voltage pulse.

[0017] Xenon gas lamps are frequently made from glass tubes which areformed into semicircular loops to increase the relative light intensityfrom the lamp while maintaining a relatively small form factor. Theselamps generate extremely high heat intensity as well as light intensity,and therefore, require positioning of the lamps so as to not cause heatbuildup in nearby components. The glass tube of a xenon lamp is usuallymounted on a light-based pedestal which is sized to fit into an openingin the light fixture and to hold the heat generating tube surface in alight fixture compartment which is separated from other interiorcompartment surfaces. In a vehicle application, the light and basepedestal are typically sized to fit through an opening in the lightfixture which is about 1 inch in diameter. The light fixture componentmay have a glass or plastic cover made from colored material so as toproduce a colored lighting effect when the lamp is ignited. Xenon gasdischarge lamps naturally produce white light, which may be modified toproduce a colored light, of lesser intensity, by placing the xenon lampin a fixture having a colored lens. The glass tube of the xenon lamp mayalso be painted or otherwise colored to produce a similar result,although the light illumination from the tube tends to dominate thecoloring; and the light may actually have a colored tint appearancerather than a solid colored light. The color blue is particularly hardto produce in this manner.

[0018] Because a preferred use of xenon lamps is in connection withemergency vehicles, it is particularly important that the lamp becapable of producing intense coloring associated with emergencyvehicles, i.e., red, blue, amber, green, and clear.

[0019] When xenon lamps are mounted in vehicles, some care must be takento reduce the corroding effects of water and various chemicals,including road salt, which might contaminate the light fixture.Corrosive effects of moisture may destroy the trigger wire and the wirecontacts leading to the anode and cathode. Corrosion is enhanced becauseof the high heat generating characteristics of the lamp which maysignificantly increase the temperature of the air inside the lampfixture when the lamp is in use, and this heated air may condense whenthe lamp is off to buildup moisture inside the fixture. The buildup ofmoisture may result in the shorting out of the electrical wires anddegrade the performance of the emission wire, sometimes preventingproper ionization of the gas within the xenon gas discharge lamp.

[0020] Warning lights, due to the type of light source utilized, may berelatively large in size which in turn may have adverse affects uponadjacent operational components. In addition, there is an increasedlikelihood for a breakdown requiring repair or replacement of enlargedcomponents.

[0021] The known warning signal lamps generally emanate large amounts ofheat which is difficult to dissipate from the sealed light bar oremergency light area and may damage the electronic circuitry containedtherein.

[0022] Another problem with the known warning signal lights is the useof rotational and/or oscillating mechanisms which are utilized to imparta rotational or oscillating movement to a light source for observationduring emergency situations. These mechanical devices are frequentlycumbersome and difficult to incorporate and couple into variouslocations about a vehicle due to the size of the device. Thesemechanical devices also frequently require a relatively large powersupply to operate the device to impart rotational and/or oscillatingmovement for a light source. Power consumption of electrical componentsfor an emergency vehicle is of primary consideration for vehicleoperators.

[0023] Another problem with the known warning signal lights is theabsence of variable intensity for the light sources which increases thenumber of available distinct and independent visual light effects. Incertain situations it may be desirable to provide a variable intensitylight signal or a modulated intensity for a light signal to create aunique light effect to facilitate observation by an individual. Inaddition, the provision of a variable or modulated intensity for a lightsignal may further enhance the creation of a unique desired light effectfor observation by an individual.

[0024] Another problem with the known warning signal lights is theinability to readily add, remove or otherwise manipulate and interchangethe individual light sources within the warning signal light. It hastypically been the case in prior warning signal lights that anindividual light source could only be manipulated to the extent that asingle light source was replaced with another individual light source.In the present invention, each LED module may have one or moreindividual LED light sources. The LED modules may have a wide variety ofshapes and sizes. A given LED module may be replaced with any other LEDmodule as desired by an individual. For example, an LED module having acylindrical shape and a single LED mounted thereon may be interchangedwith a planar module having several LEDs on one or more faces of themodule. Additionally, the present invention may include one or moresupports having a plurality of connection surfaces for receiving a likenumber of modules. Alternatively, each LED module may include one ormore colors of LED light sources for the provision of a warning lightsignal.

[0025] No warning lights are known which are flexible and which utilizea variable light intensity to modify a standard lighting effect. Thewarning lights as known are generally limited to a flashing lightsignal. Alternatively, other warning signal lights may provide asequential illumination of light sources. No warning or utility lightsignals are known which simultaneously provide for modulated and/orvariable power intensity for a known type of light signal to create aunique and desirable type of lighting effect.

[0026] No warning signal lights are known which provide an irregular orrandom light intensity to a warning signal light to provide a desiredtype of lighting effect. Also, no warning light signals are known whichprovide a regular pattern of variable or modulated light intensity for awarning signal light to create a desired type of lighting effect.Further, no warning light signals known which combine a type of lighteffect with either irregular variable light intensity or regularmodulated light intensity to provide a unique and desired combinationlighting effect.

[0027] In addition, no warning light signals are known which havemodular light sources that may be added, removed or interchanged upon alight support with other, different or similar, light source modules.

[0028] It may also be necessary to provide alternative colored LED lightsources which may be electrically controlled for the provision of anydesired pattern of light signals such as flashing, oscillating,modulating, rotational, alternating, and/or strobe light effects withoutthe necessity of spatially inefficient and bulky mechanical rotationaldevices. A need exists to provide a spatially and electrically efficientLED light source for use on an emergency or utility vehicle whichprovides the appearance of rotation without the necessity of amechanical rotational device. In addition, a need exists to provide aspatially and electrically efficient LED light source for use on anemergency vehicle which provides a flashing, modulated, oscillating,rotational, alternating, and/or strobe light effects without thenecessity of mechanical devices.

[0029] In view of the above, there is a need for a warning signal lightthat:

[0030] (1) Is capable of producing multiple light signals;

[0031] (2) Produces the appearance of a revolving or oscillating lightsignal without relying upon mechanical components;

[0032] (3) Generates little heat;

[0033] (4) Uses substantially less electrical current;

[0034] (5) Produces significantly reduced amounts of electromagneticemissions;

[0035] (6) Is rugged and has a long life cycle;

[0036] (7) Produces a truer light output color without the use offilters;

[0037] (8) Reduces current draw upon an emergency vehicle power supply;

[0038] (9) Is positionable at a variety of locations about an emergencyvehicle;

[0039] (10) Provides variable power intensity to the light sourcewithout adversely affecting the vehicle operator's ability to observeobjects while seated within the interior of the vehicle; and

[0040] (11) Has a modular construction allowing a variety of lightsource modules to be readily manipulated and interchanged one or morelight supports.

Each of the light emitting diodes (LED's) may haveshoulder portion 38 adjacent LED support 12 and dome 36. LED's 30 aresituated to be in electric communication with controller 50 and a powersupply, a battery, or power source. The use of light emitting diodes(LED's) to replace traditional halogen, incandescent, or gaseousdischarge xenon lamps reduces heat generation, current draw, andelectromagnetic emissions, while increasing lamp life and producing amore true output light color.

[0132] The controller 50 is used to selectively activate columns 32,rows 34, or individual LED's 30, to illuminate any number of a pluralityof visually distinct types of warning light signals at any moment; toilluminate more than one of a plurality of visually distinct types ofwarning light signals simultaneously at any moment; to illuminate one ofa plurality of combinations or patterns of visually distinct warninglight signals at any moment, or over any desired period of time, or toilluminate more than one of a plurality of combinations or patterns ofvisually distinct warning light signals over any desired period of time.The plurality of visually distinct warning light signals may include,but are not necessarily limited to, a strobe light signal, a pulsatinglight signal, an alternating light, a modulated light signal, a flashinglight signal, the illusion of a rotating or an oscillating light signal,a reverse character message, or images such as arrows. It should benoted that the controller 50 may also incorporate into any selectedwarning light signal variable or modulated power intensity to facilitatethe provision of a desired unique lighting effect. For example, thecontroller 50 may illuminate one or more LED light sources 30 toestablish a single warning light signal at a given moment.Alternatively, the controller 50 may illuminate one or more lightemitting diode light sources 30 to provide two or more warning lightsignals at any given moment. Further, the controller 50 maysimultaneously, consecutively, or alternatively, illuminate one or moreLED light sources 30 to establish any desired combination or pattern ofilluminated visually distinct warning light signals at any given momentor over a desired period of time. The combination and/or pattern ofvisually distinct warning light signals may be random or may be cycledas desired by an individual. The illumination of one or more patterns orcombinations of warning light signals facilitates the continuedobservation by an individual. Occasionally, the concentration orattention of an individual is diminished when exposed to a repetitive orto a monotonous light signal. The desired purpose for illumination of awarning light signal is thereby reduced. The provision of a pattern,combination, and/or random illumination of visually distinct warninglight signals maximizes the concentration or attention to be receivedfrom an individual observing a warning light signal. The purpose of thewarning light signal is thereby promoted.

[0133]FIGS. 11A, 11B, and 11C show an embodiment of controller 50capable of selectively activating columns 32, rows 34 or individualLED's 30. Controller 50 generally comprises microprocessor 52 andcircuitry 53 and is preferably contained within, attached to, or anelement of, LED support 12. It is envisioned that controller 50 may beprogrammed by an external controller 55 and powered through cable R.

[0134] In one embodiment, controller 50 generally comprises circuitboard 54 or LED mounting surface having microprocessor 52 attached to alow voltage power supply, battery, or electrical source 56.Microprocessor 52 is configured through circuitry 53 to selectivelyactivate columns 32 of LED's 30. Transistors Q9 and Q10 are inelectronic communication with microprocessor 52, power supply, battery,or electrical source 56, and their respective columns 32.9 and 32.10 ofLED's 30. Columns 32 of LED's 30 are connected to transistors Q1-Q8,which are in turn connected to microprocessor 52 through resistorsR1-R8. Microprocessor 52 is capable of selectively activatingtransistors Q1-Q8 to allow current flowing through transistors Q9 andQ-10 to activate the selected column 32 of LED's 30. This circuit iscapable of producing a strobe light signal, an alternating light signal,a modulated signal, a revolving light signal, a pulsating light signal,an oscillating light signal, or flashing light signal, a reversecharacter message, or images such as arrows.

[0135] In one embodiment, a rotating or oscillating light signal may beestablished by the sequential illumination of entire columns 32 of LED's30 by turning a desired number of columns on and then sequentiallyilluminating one additional column 32 while turning another column 32off. Alternatively, the rotating or oscillating warning light signal maybe created by selectively activating columns 32 of LED's 30. Thefollowing algorithm may be used to provide a counterclockwise revolvinglight signal (FIG. 9):

[0154] 20) return to step 1).

[0155] A clockwise revolving light signal may be created by performingsteps 1-19 in descending order then repeating the steps. An oscillatinglight signal may be created by performing: (a) steps 7 through 16 inascending order; (b) steps 7 through 16 in descending order; and (c)repeating (a) and (b).

[0156] A second embodiment of controller 50 provides a means foractivating LED's 30 individually to allow for greater flexibility in thetype of warning light signal created. This embodiment of the inventionis capable of displaying information in different colors or patterns.Depending on the size of the display, it may be necessary to scroll thesymbols or characters across the display to accommodate for a largervisual appearance. It is envisioned that the mirror image of patterns,symbols, or characters could be displayed making the message easilyreadable by drivers viewing the signal in a rear view mirror. It is alsoenvisioned that this embodiment of the invention could display arrowsindicating a direction a vehicle is to travel or other images as shownin FIG. 2. In addition, combinations of warning signal lights, directionarrows, and other information carrying signals or images, could bedisplayed simultaneously by the invention.

[0157] LED support 12 is envisioned to have several embodiments. Oneembodiment, shown in FIG. 9, consists of a panel 14 having front 16,back 18, top 20, bottom 22 and sides 24. LED's 30 are arranged on front16, with domes 36 extending therefrom, in columns 32 and rows 34. LED's30 are in electric communication with controller 50 which may becontained or sealed within LED support 12 to provide protection from theelements.

[0158] Another embodiment of warning signal light 10 is depicted in FIG.10. Here, the backs 18 of two panels 14 are attached together to allowfor a light signal to be produced on two sides. The two panels 14 formLED support 12. Alternatively, it is envisioned that a single panel 14having LED's arranged about front 16 and back 18 could be used as well.

[0159]FIGS. 6 and 8 show further embodiments of warning signal light 10.In FIG. 8, panels 14 are used to form an LED support 12 having foursides and generally shaped as squared. FIG. 6 shows panels 14 connectedto form an LED support 12 having three sides and generally triangular inshape. In both embodiments, LED's 30 are arranged about the fronts 16 ofthe panels 14. It is further envisioned that panels 14 may be integralto each other.

[0160] Yet another embodiment of warning signal light 10, consists of aflexible panel 14 and controller 50 to allow LED support 12 to be formedinto various shapes. FIG. 5 shows LED support 12 formed into a cylinder.Further variations include the use of flexible panels 14 to form othershapes such as semicircles (FIG. 12) or to simply conform to a surfaceof an emergency vehicle (FIGS. 13 and 14). This embodiment isparticularly useful for undercover vehicles which generally position thewarning signal lights inside the vehicle. For example, panel 14 could beattached to the front, rear, or side window of an undercover policevehicle.

[0161] It should be noted that numerous other shapes could be formedfrom panels 14 including those formed from combinations of flat, curved,and flexible panels at the preference of an individual.

[0162] In each of the embodiments discussed above, the array of LED's 30may be formed of the same or differently colored LED's. Generally, eachcolumn 32 or row 34 may consist of a series of differently coloredLED's. Controller 50 may be configured to select the color of the LED'sto be illuminated forming the light signal. Accordingly, the user mayselect a blue, red, white, yellow, green, or amber color or anycombination thereof to be used as the color of light signal.Alternatively, the warning signal 10 may be formed of individual LED's30 which may be selectively illuminated at the discretion of anindividual.

[0163] It is also envisioned that the controller 50 may control warningsignal lights 10 having multiple sides (FIGS. 5, 6, 8, and 10) such thateach side is capable of producing warning light signals or combinationwarning light signals that are independent and/or different from thoseproduced upon the other sides. For example, the squared shape warningsignal light shown in FIG. 8 may produce or simulate a red revolvinglight on first side 15.1, while second side 15.2 is simultaneouslyproducing a blue oscillating light, while third side 15.3 is producingor simulating a stationary white light, and while fourth side 15.4 isproducing a white strobe light.

[0164] Another embodiment of warning signal light 10 is depicted inFIGS. 1 and 2 as light bar 70 which extends from driver side 100 topassenger side 102 of emergency vehicle 104. Cover 82 protects light bar70 from the elements. Each side of light bar 70 may have LED's 30 toproduce or simulate warning light signals on each side of emergencyvehicle 104. Furthermore, controller 50 may be used to create multiplewarning light signals on each side of light bar 70. For example,controller 50 may create a simulated revolving blue light positioned atfront passenger side 102 of light bar 70, oscillating white lightspositioned at front driver side 100, and yellow arrows there between.Additional or alternative warning light signals may be produced out theback 18 and sides of light bar 70. It is further envisioned that lightbar 70 may consist of a single light source 30, a single row of lightsources 30 or a large array of light sources 30 across each side (notshown). This embodiment provides the largest display and, therefore, isbest suited to display desired combinations of warning lights andimages. It should be noted that the identified types of warning lightsignals, combinations and/or patterns of warning light signals, may alsobe reproduced through the illumination of a single row of LED lightsources 30.

[0165] Mechanical rotation and oscillation of warning signal lights 10about axis A is possible by way of attachment to gyrator 90 depicted inFIG. 3. Gyrator 90 mounted to light bar 70, generally comprises electricmotors 96 having cables 97. Gyrator 90 is configured to receiveconnecting portion 40 of warning signal light 10. Cable 97 is preferablyconnected to a power supply and either an external controller 55 orcontroller 50.

[0166] Gyrator 90 may be capable of rotating or oscillating warningsignal light 10 about a single or dual axis of rotation A. FIG. 3 showsgyrator 90 configured to rotate or oscillate warning signal light 10about a vertical axis A by way of motor 96.1 and oscillate warningsignal light 10 about a horizontal axis A by way of motor 96.2. Rotationor oscillation of warning signal light 10 about vertical axis A isaccomplished through direct attachment of connecting portion to motor96.1. Oscillation of warning signal light 10 about horizontal axis A isaccomplished by attaching swivel arm 99 to bracket 99.1 and post 99.2which is mounted to motor 96.2.

[0167] Alternative methods for imparting rotation or oscillation motionto warning signal light 10 may be accomplished through the use ofelectric motors, toothed gears, and worm gears. In addition, maintainingelectrical communication between a power supply and an externalcontroller 55 with a revolving or oscillating warning signal light 10may be accomplished using brushes or other means without sacrificing theoperation of the warning signal light 10.

[0168] In another embodiment as depicted in FIGS. 13 and 14, emergencyvehicle 104 may include a front or rear windshield 106. The front orrear windshield 106 is generally angularly offset with respect to thevehicle at an approximate angle of 45 degrees. In this embodiment, themounting of a panel 14 of light sources 30 in flush contact with theinterior of a front or rear windshield 106 occurs through the use ofangular offsets 108 for the light sources 30 such that light emittedfrom the light sources 30 occur at a horizontal visual line (V) which issubstantially parallel to the plane of a vehicle and not at anapproximate angle of 45 degrees upward, which corresponds to the anglefor the front or rear windshield 106.

[0169] In this embodiment, the ease of visualization of the light source30 is significantly enhanced by the downward angular offsets 108 whichposition the light sources 30 along parallel visual lines of sight (V).LED supports 12 or panels 14 may then be positioned in any desiredlocation within the interior of a vehicle in flush contact or proximateto the front or rear windshield 106. A suitable cable 97 is required toprovide electrical power for illumination of the light sources 30. Itshould be noted that the angle of incidence for the angular offsets 108may vary considerably dependent upon the make or model for the vehicleto include the warning signal lights 10.

[0170] It should be further noted that the warning signal light 10 maybe used with an automobile, motorcycle, snowmobile, personal watercraft, boat, truck, fire vehicle, helicopter, and/or any other type ofvehicle receptive to the use of warning signal lights 10. It should befurther noted that LED support 12 or panel 14 may be mounted to theinterior top dashboard of a vehicle proximate to the front windshield106 or to the interior top rear dashboard proximate to the rearwindshield 106 of a vehicle.

[0171] Mounting of a light support 12 or panel 14 to either the front orrear dashboards may minimize the necessity for inclusion of angularoffset 108 for the light sources 30. It should be further noted that LEDsupports 12 or panels 14 may be releasably affixed to the interior ofthe front or rear windshields 106 via the use of suction cups,hook-and-loop fabric material such as Velcro®, and/or any otherreleasable affixation mechanism at the preference of an individual. Anindividual may then adjust and reposition the location of the lightsupport 12 or panels 14 anywhere within the interior of a vehicle asdesired for maximization of visualization of the warning signal lights10.

[0172] In another alternative embodiment as depicted in FIG. 15, warningsignal light 10 may function as a remote, revolving, or stationarybeacon. In this embodiment, LED support 12 or panel 14 is preferablyreleasably connected to a transportable support 120 via the use of abracket. The transportable support 120 may be a tripod havingtelescoping legs or may be any other type of support as preferred by anindividual. In this embodiment, LED light support 12 or panel 14 iselectrically connected to an elongate electrical extension cable 97which may include any desired adapter for electrical connection to apower source which may be a vehicle. The remote light support 12 orpanel 14 may also include plug-in adapters for electrical connection toany desired electrical power source other than a vehicle as isavailable.

[0173] The transportable support 120 may also include gyrator 90 asearlier described to provide a desired rotational or oscillatory motionfor warning signal light 10. A controller 50 having a microprocessor 52may also be integral to, or in electrical communication with, LED's 30for the provision of multi-colored lights, flashing, alternating,modulated, moving characters, arrows, stroboscopic, oscillating and/orrevolving warning light signals as desired by an individual. In thisembodiment, the warning signal light 10 may be physically separated froman emergency vehicle 104 any desired distance to facilitate or enhancethe safety of a potentially dangerous situation necessitating the use ofwarning signal lights 10. In addition, it should be noted that a seriesof remote warning signal lights 10 may be electrically coupled to eachother for any desired distance to again facilitate the safety of asituation necessitating the use of warning signal lights 10.

[0174]FIG. 16 shows a perspective view of a xenon lamp 1. Xenon lamp 1has a base pedestal 2 which is typically formed of rubber, plastic, orother insulating material. Base pedestal 2 has a top surface 3 which maysupport a glass tube 4 which may have a looped curve such that an anodeend and a cathode end are each supported on a top surface. The anode andcathode ends may be sealed and respective electrical conductors 5 and 6may pass through the sealed ends and through the top surface 3. Atrigger wire 7 may be helically wound about the exterior surface of theglass tube 4 and the ends of the trigger wire 7 may be passed throughthe top surface 3 of the base pedestal 2 to form a third conductor onthe underside of the base pedestal 2.

[0175] Base pedestal 2 may have an upper cylinder portion 8 extendingfrom a lower shoulder all of which may extend above the top surface 3.The upper cylindrical portion 8 may include an upper shoulder 9. A glassdome (not shown) may be sized to fit over the xenon lamp 1 and glasstube 4 for resting on the upper shoulder 9. The glass dome may bepreferably made from a transparent or silicate glass material capable ofwithstanding heat stress. The outer diameter of the glass dome istypically about one inch which is sized to fit through the conventionalopening in a typical vehicle lamp fixture. The exterior glass domesurface typically has a much lower temperature during operation than theexterior surface of the glass tube 4 forming a part of the xenon lamp 1.The temperature drop between the glass tube 4 and the glass domefacilitates the use of coloring of the dome to provide a colored lamp byvirtue of the xenon light intensity passing through the colored dome.

[0176] The xenon lamp 1 is preferably aligned for insertion into aconventional opening 248 of a light reflector 260 (FIGS. 20 and 21). Thelight receptacle opening 248 in the light reflector 260 is typicallyabout one inch in diameter; and the glass dome and base pedestal 2 arepreferably sized to fit within the light receptacle opening 248. Thexenon lamp 1 in its final construction may include a cover plate (notshown) affixed over the bottom opening of the base pedestal 2 foraffixation to a light reflector 260 via the use of screws which passthrough the screw apertures 9.1. The anode, cathode, and trigger wire 7preferably traverse the base pedestal 2 and may include a plug 9.2 whichis adapted for engagement to a controller/power supply for a motorvehicle.

[0177] The light reflector 260 may be a conventional light reflector ofthe type found in vehicles having a clear plastic or glass lens cover.The glass or lens cover may be fitted over the front edge of thereflector 260 in a manner which is conventional with vehicle lamps. Itshould be noted that the light reflector 260 may be parabolically orother shaped at the preference of an individual. The light reflector 260may be mounted to a motor for rotation about a vertical axis. In thisembodiment the light source/replacement lamp 200 may be integrallyconnected or affixed to the reflector 260 for simultaneous rotationabout the vertical axis during use of the motor. Alternatively, thelight source/replacement lamp 200 may be fixed proximate to the verticalaxis where the light reflector 260 is rotated around the stationaryreplacement lamp 200 to provide for the visual appearance of arotational light source.

[0178] The glass domes as used with the xenon lamps 1 may be coloredwith any color as preferred by an individual including but not limitedto red, blue, amber, green, and/or white. It should be noted that thelight fixture incorporating the light reflector 260 may be a headlightfixture or a turn signal light fixture where the xenon lamp 1 is mountedinto the light reflector 260 on either side of a centrally-mountedhalogen light bulb which may be used as a headlight lamp. In this case,the light fixture could perform its normal function as a headlight andcould alternatively flash several additional colors, depending upon theneeds of the user. This configuration provides an emergency flashinglight construction which is wholly concealed within a normal head lampof a vehicle and is, therefore, not readily visible from outside thevehicle unless the lights are flashing. This construction may findapplication in an unmarked emergency vehicles such as might be used bysome law enforcement officers.

[0179] In operation, the LED replacement lamp 200 may be constructed asa replacement part for a conventional incandescent or xenon gaseousdischarge lamp. The standard mounting base 204 and LED support assembly212 may be sized to readily fit into the same light opening as anincandescent lamp would require, although it is apparent the electricaldriving circuit for the LED replacement lamp 200 may requiremodifications to accommodate the LED operating principles.

[0180] LED warning signal lamp 200 may be used in a variety of locationsabout a vehicle. It should be noted that the use of the LED warningsignal lamps 200 are not necessarily limited to positioning adjacent tothe head lamp or headlight, tail light, or turn signal illuminationdevices for an emergency vehicle 104. The LED warning signal lamp 200may be used as a rotational, pulsating, or oscillating reflector lightwithin the interior adjacent to a front, rear, and/or side window of avehicle.

[0181] It is also envisioned that the controller 50 may control warningsignal lights 200 independently of one another such that each warningsignal lamp 200 is capable of producing warning light signals which areindependent and/or different from those produced at another locationabout an emergency vehicle 104. For example, a front left location mayproduce a red colored light while simultaneously a front right locationmay produce an amber colored light and a right rear location may producea green colored light and a left rear location may produce a bluecolored light. The controller 50 may then alternate the color of thelight illuminated from the warning signal lamp 200 in each area asdesired by an individual. Alternatively, the controller 50 maysequentially activate warning signal lamps 200 positioned about anemergency vehicle 104 to simultaneously produce a desired color oralternating sequence of colors. It should also be noted that thecontroller 50 may simultaneously illuminate all LED warning signal lamps200 to produce a flashing or strobe light which may be particularlyuseful in certain emergency situations. It should be further noted thatthe controller 50 may selectively illuminate individual LED warningsignal lamps 200 in any desired color, pattern, and/or combination asdesired by an individual.

[0182] Referring to FIG. 17 in detail, an LED replacement lamp 200 isdepicted. In this embodiment the LED replacement lamp 200 includes astandard mounting base 204 which preferably includes a top surface 206.Extending upwardly from the top surface 206 is preferably an uppercylindrical portion 208 which includes an upper shoulder 210. Extendingupwardly from the upper shoulder 210 is preferably an LED supportassembly 212 which includes one or more LED lamp modules 213. The LEDlamp modules 213 may be of the same or different colors at thediscretion of an individual. A wire 202 is preferably in electricalcommunication with the plurality of LED lamp modules 213 to provide forelectrical communication with the controller 50 to individually activateor illuminate LED lamp modules 213 as preferred by an individual. Aplug-in connector 40 is preferably coupled to the wire 202 forengagement to the controller 50 and/or power source of an emergencyvehicle 104.

[0183] The LED replacement lamp 200 is preferably adapted to bepositioned in a one inch light receptacle opening 248 (approximate size)which has been previously placed through the backside of a reflectorassembly 260. The LED replacement lamp 200 is preferably used to replacea xenon gaseous discharge lamp or incandescent lamp as previouslymounted to a base which is inserted into opening 248 in a reflectorassembly 260. Illumination of one or more individual LED lamp modules213, as mounted in the reflector assembly 260, enables the reflectorassembly/lens to take on the appearance of a warning signal or emergencysignaling lamp. The LED replacement lamp 200 preferably replaces thexenon gaseous discharge or incandescent lamp assemblies with highbrightness, long life LED technology.

[0184] Referring to FIG. 18, an incandescent lamp or quartz halogen H-2lamp is depicted and in general is indicated by the numeral 220. Theincandescent lamp assembly 220 is preferably formed of a standardmounting base 222. A vertical post 224 preferably extends upwardly fromthe standard mounting base 222. The incandescent light bulb 226 ispreferably mounted in the vertical post 224. The vertical post 224 mayextend below the standard mounting base 222 to provide for electricalcoupling with a wire 228 which preferably includes a standard pinconnector 230. The standard pin connector 230 is preferably adapted forelectrical communication to a power supply and/or controller 50 foractivation of the incandescent lamp assembly 220. The incandescent lampassembly 220 may be stationary or mounted in a rotational lightreflector 260 as desired by an individual. The light bulb 226 may be ahalogen H-2, 55 watt, lamp at the discretion of an individual.

[0185] As depicted in FIG. 19, LED replacement lamp 200 is adapted toreplace the incandescent lamp assembly 220 in a stationary or rotationallight reflector 260. The LED replacement lamp 200 as depicted in FIG. 19preferably includes a standard mounting base 234 and a vertical post236. It should be noted that the vertical post 236 may extend upwardlyfrom the standard mounting base 234 and may alternatively extend belowthe standard mounting base 234 at the preference of an individual. AnLED mounting area 238 may be preferably integral or affixed to the uppersection of the vertical post 236. The LED mounting area 238 preferablyincludes a plurality of individual LED module lamps 240 which may beindividually, sequentially, or illuminated in combination with otherlight sources at the preference of an individual.

[0186] The individual LED module lamps 240 are preferably in electricalcommunication with a wire 242 which includes an integral standard wireconnector 244. The wire connector 244 is preferably adapted to beplugged into a controller 50 or power supply. Communication is therebyprovided for selective illumination of the individual LED module lamps240. It should be noted that a group of individual LED module lamps 240are mounted in the LED mounting area 238. It should also be noted thatthe LED replacement lamp 200 is preferably adapted to replace theincandescent lamp assembly 220 or a xenon gaseous discharge lampassembly base of FIGS. 16 or 18. The purpose of the LED replacement lampassembly 200 is to replace existing xenon gaseous discharge andincandescent lamps with new LED technology while simultaneouslyutilizing existing standard bases in a standard lamp enclosure. Forexample, an individual may choose to replace a halogen “H-2” 55 wattlamp with an “LED-2” lamp in an existing rotating light fixture with noother structural modifications, yet achieving the advantages of lesspower consumption, greater reliability, easier installation, less RFemissions (which reduces interference with radio or electronicequipment), cooler operating temperatures, simplified circuitry, longerlife, greater durability and duty capability, and simultaneouslyproviding pure and easier-to-see color light output.

[0187] As depicted in FIG. 20, a rotational light reflector 246 isdisclosed. The rotational light fixture 246 includes a reflectorassembly 260 having a standard opening 248. The incandescent lightassembly 220 is preferably positioned in the standard opening 248 forextension of the vertical post 224 outwardly from the reflector assembly260 for positioning of the light source 30 in a desired location. Wherethe light source 30 is a standard halogen light bulb 226, the lightemitted from the standard halogen light bulb 226 preferably reflects offthe parabolic-shaped reflector assembly 260 for transmission of light ina direction as indicated by arrows AA for visualization by individuals.Reflector assembly 260 and bulb 226 may be rotated via the use of gears250 which are preferably driven by electrical motors not shown. In thismanner, the rotational light fixture 246 including the reflectorassembly 260 may be rotated at any desired velocity as preferred by anindividual.

[0188] As may be seen in FIG. 21, a rear or back view of the rotationallight fixture 246 is provided. As may be seen in FIG. 21, the lightsource is preferably positioned in the standard opening 248. The wire228 as in electrical communication with the light source and ispreferably connected via the standard pin connector 230 for electricalcommunication with a power source.

[0189] As depicted in FIG. 22, an alternative rotational light fixture252 is depicted. Rotational light fixture 252 preferably includes areflector assembly 260 which may be parabolic in shape for thetransmission of light along a common axis as depicted by arrows BB forvisualization by an individual. In this embodiment, the individual LEDmodule lamps 240 may be positioned to the front of the reflectorassembly 260 through the use of a frame 254. The frame 254 may beintegral or connected to a gear 250 as desired by an individual. Thegear 250 may be driven by a motor for rotation of the light fixture 252.It should be noted that the individual LED module lamps 240 arepreferably in electrical communication with a power source not shown.

[0190] It should be further noted that the rotational light fixture 252may also be adapted for the provision of an oscillating or pulsatingwarning light signal at the preference of an individual.

[0191] An alternative replacement LED lamp 200 is depicted in FIGS.23-25. In this embodiment the LED replacement lamp 200 includes astandard mounting base 270. The standard mounting base 270 alsopreferably includes a plurality of teeth 272. The teeth 272 arepreferably adapted for mating coupling with gears integral to a motorand/or reflector 260, or rotational light fixture 246 to facilitaterotation and/or oscillation of the replacement LED lamp 200. Thestandard mounting base 270 also preferably includes a top surface 274opposite to the teeth 272.

[0192] An upper cylinder portion 276 is preferably adjacent to the topsurface 274. The upper cylinder portion 276 preferably includes an uppershoulder 278. Extending upwardly from the upper shoulder 278 ispreferably a circuit board, LED mounting surface, or support 280 whichpreferably includes one or more LED illumination sources 282. The LEDillumination sources 282 may be of the same or different colors at thepreference of an individual. A wire 284 is preferably in electricalcommunication with the LED illumination sources 282 to provide forcommunication and contact with the controller 50 for combination and/orindividual illumination of the LED illumination sources 282. A standardplug-in connector may be integral to the wire 284 to facilitate couplingengagement to the controller 50 and/or power source for a vehicle 104.

[0193] The circuit board or LED mounting surface 280 is preferablyadapted to have a first side 286 and an opposite side 288. Preferably aplurality of LED illumination sources 282 are disposed on both the firstside 286 and the opposite side 288 of the replacement lamp 200.

[0194] A glass dome or protector 290 is preferably adapted forpositioning over the circuit board or LED mounting surface 280 forsealing engagement to the top surface 274 of the standard mounting base270. The glass dome 290 may be formed of transparent plastic material ora transparent or silicate glass material capable of withstanding heatstress at the preference of an individual. It should be further notedthat the glass dome 290 preferably protects the circuit board or LEDmounting surface 280 and the LED illumination sources 282 fromcontamination and from exposure to moisture during use of thereplacement lamp 200. In this regard, the sealing lip 292 of the glassdome 290 preferably is securely affixed to the top surface 274 toeffectuate sealing engagement therebetween. The outer diameter of theglass dome 290 is preferably about one inch which is sized to fit withinthe conventional opening 248 in a typical lamp fixture or reflectorassembly 260.

[0195] The replacement lamp 200 depicted in FIGS. 23, 24, and 25 is alsoadapted to be positioned in a one inch light receptacle opening 248which has been placed into a reflector assembly 260. Illumination of oneor more individual LED illumination sources 282 as disposed on thecircuit board or LED mounting surface 280 enables the replacement lamp200 to take on the appearance of a warning signal or emergency signalinglamp.

[0196] The replacement lamp as depicted in FIGS. 23, 24, and 25 mayalternatively permit the circuit board 280 to extend below the uppershoulder 278 to facilitate affixation and positioning relative to thestandard mounting base 270.

[0197] The controller 50 may regulate the illumination of the LED lightsources 282 individually, or in combination, to provide a desiredwarning lighting effect for the replacement lamp 200. Also, thecontroller 50 may illuminate the LED light sources 282 individually, orin combination, independently with respect to the first side 286 and theopposite side 288 to provide different warning light effects to beobserved by an individual. The controller 50 may also simultaneously orindependently regulate the power intensity exposed to the LEDillumination sources 282 to provide for a modulated or variable lightintensity for observation by an individual. It should also be noted thatthe LED illumination sources 282 may be formed of the same or differentcolors at the preference of an individual to provide a desired type ofwarning light effect for the replacement lamp 200.

[0198] In an alternative embodiment, the LED warning signal lamps 10 orLED replacement lamps 200 may be electrically coupled to a controller 50which in turn is used to provide a modulated power intensity for thelight source. A modulated power intensity enables the provision ofvariable power output or patterns of illumination for creation of aplurality of visually distinct warning light signals without the use ofmechanical devices. In these embodiments, the controller 50 illuminatesselected light sources 282 and the controller 50 may also regulateand/or modulate the power supplied to the light source 282 therebyvarying the intensity of the observed light. In addition, the controller50 may modulate the power supplied to the LED warning signal lamps 10 orLED replacement lamps 200 in accordance with a sine wave pattern havinga range of 0 to full intensity. At the instant of full intensity, thecontroller 50 may also signal or regulate a power burst for observationby an individual. The controller 50 operating to regulate and/ormodulate the power intensity for the warning signal lamps 10 or LEDreplacement lamps 200 in conjunction with illumination andnon-illumination of selected light sources 282 may establish theappearance of a rotational warning light signal or pulsating lightsignal without the necessity of mechanical rotational or oscillatingdevices. The current draw requirements upon the electrical system of anemergency vehicle 104 is thereby significantly reduced. Spatialconsiderations for an emergency vehicle are also preferably optimized byelimination of mechanical, rotational and/or oscillation devices.

[0199] The controller 50 may also regulate the modulated power intensityfor the provision of a unique variable warning light effect. The uniquevariable intensity light source is not required to cycle through a zerointensity phase. It is anticipated that in this embodiment that therange of intensity will cycle from any desired level between zero powerto full power. A range of power intensity may be provided between thirtypercent to full power and back to thirty percent as regulated by thecontroller 50. It should also be further noted that an irregular patternof variable power intensity may be utilized to create a desired type ofnon-repetitive warning light effect. In addition, the controller 50 mayalso sequentially illuminate adjacent columns 32 to provide a uniquevariable rotational, alternating, oscillating, pulsating, flashing,and/or combination variable rotational, alternating, pulsating,oscillating, or flashing visual warning light effects. A pulsatingwarning light signal may therefore be provided through the use ofmodulated power intensity to create a varying visual illumination orintensity effect without the use of rotational or oscillating devices.The controller 50 may also modulate the power intensity for anycombination of light sources 30 or 282 to provide a distinctive orunique type of warning light signal.

[0200] The use of a controller 50 to provide a modulated power intensityfor a light source may be implemented in conjunction with replacementlamps 200; flexible circuit boards having LED light sources 30; paneledcircuit boards or LED mounting surfaces having LED light sources 30;light bars 70, having LED light sources 30; a cylindrical, square,rectangular, or triangular-shaped circuit boards having LED lightsources 30; modules 606, and light supports 602, as seen in FIGS. 33 and38-40, and/or any other type or shape of LED light sources including butnot limited to the types depicted in FIGS. 1-42 herein.

[0201] Further, the controller 50 may be utilized to simultaneouslyprovide modulated or variable light intensity to different and/orindependent sections, areas, and/or sectors of a light source. Also, thecontroller 50 may be utilized to simultaneously provide modulated orvariable light intensity to different and/or independent sectors, areas,and/or sections of the forward facing side or rearward facing side ofthe light bar 70 for the provision of different warning light signals ora different warning light effects on each side. In this embodiment it isnot required that the forward facing and rearward facing sides of thelight bar 70 emit the identical visual patterns of illuminated lightsources 30. The controller 50 may regulate and modulate the variablelight intensity of any desired sector of the forward facing sideindependently from the rearward facing side or sector of the light bar70. The controller 50 may thereby provide any desired pattern and/orcombination of patterns of warning light signals through the utilizationof variable and/or modulated light intensity for the forward facingside, and a different type or set of patterns and/or combination ofpatterns of warning light signals having variable or modulated lightintensity for the rearward facing side of the light bar 70 as desired byan individual. It should be further noted that an infinite variety ofpatterns and/or combinations of patterns of warning light signals may beprovided for the forward facing side and the rearward facing side of thelight bar 70 a the preference of an individual.

[0202] The use of the controller 50 to modulate the power intensity fora light source 30 to provide a unique warning light signal may beutilized within any embodiment of an LED light signal 10, light bar 70light support, replacement lamp 200 or reflector assembly as describedin FIGS. 1-42 herein.

[0203] It should be further noted that the modulation of the powerintensity for a light source 30 or replacement lamp 200 may be used inconjunction, or as a replacement to, the sequential illumination ofrows, columns, and/or individual LED light sources 30 to provide adesired type of unique warning light effect.

[0204] The modulated power intensity may be regulated by the controller50 to create a unique warning light signal within a single sector or inconjunction with multiple separated or adjacent sectors of light bar 70or a light support for the provision of any desired composite emergencywarning light signal. All individual LED light sources 30 within a lightbar 70 or light support may be simultaneously exposed to incrementallyincreased modulated power intensity to provide for an incrementalincrease in illumination. A power burst at full power may be provided atthe discretion of an individual. The modulation of the power intensityin conjunction with the incremental increase in illumination of all LEDlight sources 30 within light bar 70 or light support may provide theappearance of rotation of a warning light signal when observed by anindividual. The power exposed to the individual light sources 30 maythen be incrementally decreased at the preference of an individual. Itshould be noted that the power is not required to be regularlyincrementally increased or decreased or terminated. It is anticipatedthat any pulsating and/or modulated variable light intensity may beprovided by the controller 50 to the LED light sources 30.

[0205] It should also be noted that all individual LED light sources 30within a light bar 70 are not required to be simultaneously andincrementally illuminated to provide for the appearance of rotation. Forexample, a light bar 70 or light support may be separated into one ormore distinct segments or sectors which are formed of one or morecolumns 32 of LED light sources 30. a particular segment may be selectedas a central illumination band which may receive the greatest exposureto the modulated or variable power intensity and, therefore, provide thebrightest observable light signal. An adjacent segment may be disposedon each side of the central illumination band which in turn may receivemodulated or variable power intensity of reduced magnitude as comparedto the central illumination band. A pair of removed segments may beadjacent and exterior to the adjacent segments, and in turn, may receiveexposure to a modulated power source of reduced intensity as compared toadjacent segments. The number of desired segments may naturally vary atthe discretion of an individual. The controller 50 may thereby regulatea power source to provide a modulated or variable power intensity toeach individual segment to provide for a unique warning light effect forthe light bar 70 or light support.

[0206] It should be further noted that light supports 12 may be flat andrigid, pliable, moldable, triangular, cylindrical, partiallycylindrical, and/or any other shape as desired by an individual providedthat the essential functions, features, and attributes described hereinare not sacrificed.

[0207] The provision of a modulated power intensity to the light bar 70or light support may also be coupled with or in combination to thesequential illumination of columns 32 as earlier described. In thissituation, the warning light signal may initially be dim or off as theindividual columns 32 are sequentially illuminated and extinguished forillumination of an adjacent column or columns 32. The power intensityfor the illuminated column or columns 32 may simultaneously beincrementally increased for a combination unique rotational andpulsating modulated or variable warning light signal. In addition, thecontroller 50 may be programmed to provide the appearance of rotationalpulsation and/or oscillation at the discretion of an individual.

[0208] Each individual LED light source 30 preferably provides an energylight output of between 20 and 200 or more lumens as desired by anindividual.

[0209] Each light support 12 may also contain a plurality of rows 34 ofindividual LED light sources 30. The light supports 12 are preferably inelectrical communication with the controller 50 and power supply. Thesupports 12 preferably are controlled individually to create a desiredwarning light signal for an emergency vehicle 104 such as rotation,alternating, oscillation, strobe, flashing, or pulsating. Each support12 may be controlled as part of an overall warning light signal orpattern where individual supports 12 may be illuminated to provide adesired type or combination light signal in addition to the provision ofa modulated or variable power intensity for the light source 30.

[0210] Modulated power intensity may be regulated by the controller 50to create the appearance of rotation within a single support 12 or inconjunction with multiple separated, independent or adjacent supports 12for the provision of a composite emergency warning light signal.

[0211] It should be noted that each portion, segment, section, sector,or area of light bar 70 or light support may be controlled as part of anoverall warning light signal or pattern where individual sections orsectors may be illuminated to provide a desired type of warning lightsignal including but not limited to rotation and/or oscillation throughthe use of a modulated or variable power intensity. Alternatively, thecontroller 50 may provide for the random generation of light signalswithout the use of a preset pattern at the preference of an individual.

[0212] Controller 50 may be used to selectively activate individualLED's 30 to create a pulsating light signal, a strobe light signal, aflashing light signal, an alternating light signal, and/or analternating colored flashing light signal for an emergency vehicle.

[0213] Controller 50 provides a means for activating LED's 30individually to allow for greater flexibility in the type of warninglight signal created. This embodiment of the invention is also capableof displaying information in a variety of different colors or sequentialillumination of colors.

[0214] It should be noted that the power provided to the LED lightsources is not required to be terminated during transition betweenrepetitive light signals or between illumination of different lightsignals. For example, individual colors of LED light sources may receivea higher power output to increase illumination as compared to adifferent color of LED light source to create a preferred lightingeffect. It should also be noted that each individual LED light source isnot required to receive the same level of power output from thecontroller 50. Therefore different individual LED light sources mayreceive different power output levels within a single warning lightsignal. Individual LED light sources are not required to besimultaneously and incrementally illuminated to provide for theappearance of rotation. It is anticipated that a pulsating and/ormodulated variable light intensity may be provided by the controller 50for regulation of the power output from thirty percent to maximum andback to thirty percent which affords a desirable type of pulsatingmodulated variable light effect.

[0215] Referring to FIGS. 41 and 42, an individual LED light source 306is depicted in detail. The LED light source 306 preferably include aceramic and/or heat resistant base 334. Centrally within the ceramic andheat-resistant base 334 is positioned a light source 336. The lightsource 336 is preferably enclosed within a protective cover 338.Extending outwardly from the individual light source 306 are a pair ofcontact paddles 340 which preferably provide for the electrical contactsfor illumination of the light sources 336 during use of the individuallight sources 306. The back of the LED light source 306 includes a slug342. The slug 342 is designed to be positioned within circular openings344 of a circuit board or LED mounting surface 346. The LED lightsources 306 as depicted in FIGS. 41 and 42 preferably provide for alight intensity varying between 20 and 200 lumens or higher at thediscretion of an individual. The positioning of the slug 342 in thecircular openings 344 of the circuit board or LED mounting surface 346also preferably establishes a heat sink. A heat sink is desirablebecause the individual LED light sources 306 may have a sufficient levelof power output during use to develop heat. As a result, the slugs 342are positioned within the circular opening 344 and may be fully engagedto an adhesive for affixation to a base. This combination assists in thedissipation of heat during use of the individual LED light sources 306enhancing the performance of the light support 302.

[0216] As earlier described, the brightest or most intense light of theindividual LED light sources 306 is provided at an acute angle ofapproximately 40° to 42°.

[0217] Referring to FIGS. 26-30, a reflector or cullminator for theindividual LED light sources 306 is disclosed. The reflector orcullminator is indicated in general by the numeral 370. The reflector orcullminator 370 may be conical in shape and may be configured toencircle an individual LED light source 306. The reflector orcullminator 370 may be partially transparent. The reflectors 370 mayhave a clear section 372 and a reflective section 374. In FIG. 29, theclear section 372 is preferably positioned proximate to the LED lightsource 306 and the reflective section 374 is preferably positioned tothe top of the reflector 370.

[0218] In FIG. 28, the reflective section 374 is preferably positionedproximate to the LED light source 306 and the clear section 372 ispreferably positioned to the top of reflector or cullminator 370. As maybe seen in FIG. 30, the entire interior surface of the reflector orcullminator 370 may be formed of a reflective section 374. It should benoted that any combination of clear sections 372 and reflective sections374 may be utilized at the discretion of an individual. It should benoted that a plurality of clear sections 374 may be utilized within eachreflector or cullminator 370 at the discretion of an individual.

[0219] The use of a combination of clear sections 372 and reflectivesections 374 enable an individual to select a configuration for theprovision of partial illumination along an angle which is not parallelto a desired line of sight. An individual may thereby be able to observean illuminated light signal from the side or top of a light bar or lightsupport 302 as opposed to being aligned with a desired line of sight.

[0220] Each cullminator or reflector cup 370 preferably includes anangled interior surface which extends upwardly and diverges outwardlyfrom a central opening 394. Each central opening 394 is preferablyconstructed and adapted for positioning proximate to and over an LEDlight source 306. Each of the cullminator or reflector cups 370 alsopreferably includes an angled exterior surface which extends upwardlyand diverges outwardly from a bottom or base which is preferablypositioned approximate to an LED mounting surface or circuit board 346.

[0221] Referring to FIG. 26 a plurality of cullminator cups orreflectors 370 may be formed into a cullminator assembly or array 392.The cullminator assembly or array 392 is preferably adapted forpositioning over an array of LED light sources 306. Examples of arraysof LED light sources 306 which may be utilized with a cullminatorassembly 392 are depicted in at least FIGS. 3-10, 12, 14, 15, 23-25, 31,and 32.

[0222] Each cullminator array 392 is preferably formed of a reflectivematerial which has plurality of reflective cups 370 disposedtherethrough. Each opening 394 is adapted for positioning over an LEDlight source 306. The cullminator array 392 preferably has a sufficientthickness to establish an interior reflective surface having asufficient dimension to reflect light as emitted from the LED lightsources 306. Alternatively, the interior surface of each reflector cup370 may be entirely or partially coated with reflective material at thediscretion of an individual. It should be noted that the entirecullminator assembly 392 is not required to be formed of reflectivematerial if the interior surface of the reflector cups 370 are coatedwith reflective material.

[0223] The cullminator array 392 may be formed in any shape as desiredby an individual including but not necessarily limited to square,rectangular, triangular, linear, circular, oval, and special or otherirregular shapes for use in reflecting light emitted from an LED lightsource 306. The interior surface of any desired number of cullminatorcups 370 may also be coated with any pattern or stripes of reflective374 and non-reflective 372 sections as earlier described.

[0224] Referring to FIGS. 31 and 32 a modular light support 480 ingeneral includes an LED mounting surface 482 having one or more LEDlight sources 306, a cullminator assembly 484 and a cover 324.

[0225] The LED mounting surface 482 is preferably elongate and includesa plurality of LED light sources 306. In general, one to five LED lightsources 306 are disposed in a linear orientation along the LED mountingsurface 482 which may be a circuit board as earlier described. The LEDmounting surface 482 also preferably includes a first end 486 and asecond end 488. An opening 490 is preferably positioned through the LEDmounting surface 482 proximate to each of the first end 486 and secondend 488.

[0226] The cullminator assembly 484 preferably includes a plurality ofreflector cup areas 492. The cullminator assembly 484 preferablyincludes a plurality of support walls 494 and a top surface 496. Thecullminator assembly 484 also preferably includes a plurality ofopenings 490. Each of the openings 490 is preferably sized toreceivingly position and hold the individual LED light source 306 duringassembly of the modular light support 480. The reflector cup areas 492are preferably equally spaced along the cullminator 484 to correspond tothe spacing between the individual light sources 306 as disposed on theLED mounting surface 482.

[0227] The cover 324 is preferably transparent permitting transmissionof light emitted from the LED light supports 306 therethrough. The cover324 preferably includes a forward face 498, a pair of end faces 500, atop face 502 and a bottom face 504. Each of the pair of end faces 500preferably includes a receiving notch 506 which is adapted toreceivingly engage the LED light mounting surface 482 during assembly ofthe modular light support 480. An affixation opening 508 preferablytraverses the forward face 498 proximate to each of the pair of endfaces 500. A fastener 510 preferably passes through the affixationopening 508 for engagement to the opening 490 to secure the LED mountingsurface 482 into the receiving notch 506. It should be noted that thecullminator assembly 484 is then positioned within the interior of thecover 324 where the top surface 496 is proximate to the forward face498. The illumination of the LED light sources 306 then transmits lightthrough the forward face 498 for observation of an emergency warninglight signal.

[0228] Specifically referring to FIG. 32 one or more modular lightsupports 480 may be positioned adjacent to each other for the creationof a light bar or light stick 512. The modular light supports 480 and/orlight bar or light stick 512 may be coupled to a controller 50 which mayindependently and/or in combination provide a plurality of independentand visually distinct warning light signals as earlier described. Inaddition, the controller 50 may provide modulated and/or variable powerintensity to the individual LED light sources 306 to establish uniquewarning light signal effects. It should also be noted that thecontroller 50 may individually illuminate LED light sources 306 toprovide for one or a combination of colored light signals as desired byan individual.

[0229] Any number of modular light supports 480 may be positionedadjacent to each other to comprise a light bar or light stick 512 at thepreference of an individual. It should be further noted that a pluralityof modular light supports 480 may be positioned at any location aboutthe exterior or within the interior of a vehicle at the discretion of anindividual. In one embodiment each of the individual modular lightsupports 480 will be electrically coupled to a power supply andcontroller 50 for the provision of unique individual and visuallydistinctive warning light signals and combination warning light signalsas earlier described.

[0230] LED technology enables the selection of a desired wave length oflight energy for transmission from the individual LED light sources 306.Any wave length of visible or non-visible light is available fortransmission from the LED light sources 306. As such, generally nofilters are required for use with individual LED light sources 306. Theindividual LED light sources 306 may be selected to provide for anydesired color normally associated with the use in emergency vehiclessuch as amber, red, yellow, blue, green and/or white.

[0231] The controller 50 described herein is very versatile. Thecontroller 50 may simultaneously display any number of combinations ofwarning light signals. For example, the controller 50 may provide for asolitary light signal for transmission from a light source.Alternatively, the controller 50 may enable the transmission of twosignals simultaneously from the identical light source where a firstwarning light signal is emitted from one portion of the light source anda second warning light signal is emitted from a second portion of thelight source. Alternatively, the controller 50 may alternate the twowarning light signals where the first area of the light source firsttransmits a first warning light signal and secondly the first area ofthe light source then transmits a second warning light signal. Thesecond area of the light source may initially transmit a second warninglight signal and then the second area may transmit the first warninglight signal. Further, the controller 50 may transmit two independentand visually distinct warning light signals simultaneously withindifferent areas of light source. The controller 50 may also reverse thewarning light signals for simultaneous transmission between differentareas of the light source. Further, the controller 50 may regulate thetransmission of more than two visually distinct types of warning lightsignals from a light source at any given moment. The controller 50 mayalternate warning light signals within different areas or enabletransmission of warning light signals in reverse alternating order forthe creation of an infinite variety of patterns of visually distinctwarning light signals for use within an emergency situation. Thecontroller 50 may also permit the transmission of a repetitive patternof warning light signals or a random pattern of visually distinctwarning light signals at the preference of an individual. The patternsmay be formed of one, two, three, or more different types of lightsignals at the preference of an individual.

[0232] Turning to the embodiment shown in FIG. 33. FIG. 33 shows apossible configuration of a warning signal light 600 having modularcomponents. In the embodiment shown a light support 602 has a pluralityof module receiving ports 604. The module receiving ports 604 areconstructed and arranged to provide electrical communicationrespectively to a module support member 610 of a module 606 receivedtherein. Each of the module support members 610 may be made up ofconnection teeth or contacts 608 which electrically contact and engagethe receiving ports 604 when inserted therein. Each module 606 has atleast one visible light signal display surface 612 which has one or morelight sources 30 removably mounted thereon. Preferably the light sources30 are light emitting diodes, such as have been previously discussed.About each light source 30 may be a cullminator 370 as earlierdescribed. Furthermore, each cullminator 370 may include a reflectivesurface 616 at least partially disposed thereon. Reflector 616 moreefficiently direct the light emitted from light source 30 in a desireddirection. In an additional embodiment of the invention the reflector616 may be adjustable so as to redirect and/or focus light emitted fromthe light source 30 during use. Also, the visible surface 612 or theindividual cullminator cup 370 and reflectors 616 may also have one ormore lenses equipped thereon to provide the warning signal light withthe ability to magnify and/or diffuse emitted light as may be desired.

[0233] In the embodiment shown, the module support members 610 and themodule receiving ports 604 respectively are uniform in size. Theuniformity of the ports 604 and the members 610 allows modules 606 to bereadily replaced and also provides the invention with the capacity tohave variously sized and shaped modules 606 to be interchanged andarranged in various configurations as desired by a user. For example arelatively elongated module, such as is indicated by reference numeral606 a, could be positioned in any of the various ports 604 shown andcould likewise be replaced with any other module such as the morevertically oriented module 606 b, or the remaining module type 606 c.Such modularity and standardization of connections provides the presentinvention with a tremendous variety of module configurations which maybe readily reconfigured as desired.

[0234] In addition to providing a variety of module types, the presentinvention also provides for a variety of mechanisms to be associatedwith the ports 604. In the embodiment shown for example, a rotationmechanism 618 has a port 604 mounted thereon. Any number of rotationmechanisms could be included on the surface of the support 602 such asis shown. Alternatively a similar mechanism or mechanisms could beincluded on one or more surfaces of a module to provide a dedicatedrotation module. The rotation mechanism 618 could also be configured asa gyrator or other motion producing device.

[0235] It must also be noted however that the three types modulevarieties 606 a, 606 b and 606 c presently shown and described aremerely three examples of potential module sizes and shapes. It should beunderstood that modules 606 may be configured in any size or shape asdesired. As indicated above, in order to ensure the greatest ease of useand elegance in design, it may be desirable to provide the variousmodules 606 with uniform support members 610 and also provide thesupport 602 with similarly uniform ports 604. However, in order toensure that only certain module types are utilized in certain ports, itis recognized that the present invention could also utilize a support602 having a variety of port 604 configurations with modules 606 havingmodule supports 610 sized to correspond with specific ports and/or ports604.

[0236] In keeping with the modular construction of the presentinvention, it should also be understood that the support 602, like mostof the components thus described could be embodied in a variety ofshapes and sizes. Preferably, the support 602 is a circuit board with anumber of ports 604 included thereon. In one aspect of the invention,the support 602 could be embodied as several supports with each supporthaving a unique arrangement of modules and light sources. The electronicschematics shown in FIGS. 34-37 show some possible configurations andtheir associated electronic connections between the various componentsof the invention.

[0237] Starting in FIG. 34, an embodiment of the invention is showedwhere the controller 50 is in electronic communication with one or moresupports 602, which are in turn in electronic communication with one ormore modules 606, which are in turn in electronic communication with oneor more light sources 30. FIG. 35 shows a similar series of electricpathways, but in the present embodiment the controller 50 may also be indirect electric communication with each of the various components,support(s) 602, module(s) 606 and light source(s) 30, independent of oneanother.

[0238] In the embodiment shown in FIG. 36, the individual visiblesurfaces 612 of the various modules 606 may be controlled by thecontroller 50. Though not indicated in the schematic, the variouscomponents: supports 602, modules 606, visible surfaces 612 and lightsources 30 may be independently controlled by the controller 50 or maybe selectively activated via the electronic pathway shown.

[0239] In the embodiment shown in FIG. 37, a support 602 includes acontroller 50. Each controller 50 is in electronic communication with anexternal controller 55 in the manner previously discussed above. Theembodiment shown in FIG. 37 could include numerous independentlycontrolled supports 602 which are in communication with the externalcontroller 55. It should also be noted that individual controllers 55could also be included with each modules 606 to provide for a warningsignal light having numerous predetermined light signals or patternswhich could be displayed by sending a single signal from the externalcontroller 55 to the various controllers 50.
